T0 all w7wm ib mag concern:

Be it known that I, CONRAD TRIER, a Citizen of '(he Unlted States, residingat Chicago, in the county of Cool: and State of Illinois, have invented a new and nsoful Improvemen's in Gar-Doms, of Whid1 the following 1's a specification.

My invention rolates to the dass of cloors nsually provided npon freight-oars employed particnlarly or incidentally in the transportation of grain, which are known as graincloors, and are designecl when in use to dose only the lower portion 0f the door-opening in eaol1 sicle of the Gar, and when not in use to be' raisecl to the top of the cloor-opening and swung back to a substantially horizontal plane, whereby tl1e said op ning is left eleman l the cloor itself plaeecl in the condit-ion of being out of tl1e way.

Grain-doors of the above dass hitherto co1nmonly employed have beenarrangecl to slicle npon stationary guide-rods seourecl t0 the door-posts inside the car and 011 opposite sides 0f the door-openings. As cars usecl in the transportation of grain are also use(l largely in the transportation of otherfreight, as lu1nber, for instance, tl1e guide-rods referrecl to are frequently' in tl1e way, and are liable to become bent, displacecl, or broken in the loacling and unloading or tho jarring against the1n while in transit of freight other than grain, thereby impairing or destroying their utilityas guid es.

My object is t0 provicle a grain-door of the ab0ve dass and of improved construction, in the employment of which stationary guiclerods may be clispensed With, whereby when the cloor is turned 110 its horizontal or substantially horizontal position -no part of tho grain-door m echanism shall remain below tl1e top of the doorway Whid1 can materially interfere Witl1 the nse of tl1e ear for freight of any description or loe itself injnriously affeeted by such use.

My invention consists in tl1e general 0011- struction of 1ny improvecl graln-door, ancl also in details of constrnction ancl oo1n'binations of parts, hereinafter doscribed and clai1ned.

In the drawings, Figures 1 and 2 are views in sectional elevation 0f tl1e interior of a 'freight-car provided With myimproved graindoor in clifi'erentconditions. Fig. 3

l B are tl1e doonposts, ancl B a projection, which may be affordecl by any suitable means, as by causing the door-cap to extend into t-he car above the door-Opening.

D D areloose hangers, preferably in the for1n of metal rods, pivotally securecl at one end.to brackets 25 and providecl at their opposit-e encls Witl1 eyes s, which receive and atlorcl bearings for pins s,projeoting from tl1e lateral edges of the grain-cloor toward oho upper encl qthereof. The brackets 25 are secnred t0 the plate B of the oa1jand the r0ds D are of a length to permit the door, as lt hangs by 1neans of its pins s at tl1e eyes s in the rods, barely to touch thefioor of the car witl1 its lower edge q. The hangers thus operate to maintain the loor in a vertical position against the cl0or-posts.

E E are angle plates 01 keepers secnred to the floor 0f the car on opposite sides 0f the door-opening, ancl are arrangecl t0 altorcl 0011- fines With the cl00r-posts f01 tl1e lower plated corners m of the door to enter and fit snugly into. The keepers E aro bevelecl 011 both inner faces 7, as shown in Fig. 6, to facilitate' the entrance of the corners 00 of tl1e door and guide the said corners as the door clescends against the door-posts, 1naintaining tl1e CO1- ners, when acljusted, firmlyin oontaet with tl1e latter ancl at tl1e sa1ne time preventing lateral shifting of the (1001.
